Abstract

This doctoral project is part of the FAPESP project to develop a low-cost acoustic correlators for the Brazilian market. The aim of this doctoral project is to investigate novel signal processing procedures that can work with off-the-shelf hardware. Initially, vibro-acoustic signals of a typical water distribution system in Brazil will be characterized, as they currently are not known. Previous work has shown that there are merits in analysing the signals in both the time and frequency domains to determine the time delay associated with leak signals, and hence the location. This will be investigated for leak noise signals in Brazil and an appropriate algorithm will be developed to determine the bandwidth over which the analysis is to be conducted. The ultimate aim is to embed the new algorithm in a new prototype device which will be tested in the field. (AU)
